Hi,
I am trying the W25Q01JV flash with 1Gbit size and have problems while flashing. When I do a crc calucation after I wrote a sector (4K) I get errors on very specific sectors. All of them are the odd indices. F.e. Sector 0 (0-4095), sector 1 (8191) fails, the next one is successful again.
Just to show an example, those are the first few sectors which fail: 37, 43, 45, 67, 69, 73, 75, 77, 79, 97, 99
It seems to only happen, when I switch to FLASH_STATUS_FULL after writing the Blob. So I stopped to switch to FLASH_STATUS_FULL when writing on the flash.
But whenever I don't switch to FLASH_STATUS_FULL I cannot write more than 16 Megabyte. I get address errors back when using CMD_FLASHUPDATE (invalid address). This is the error I get when reading out RAM_ERR_REPORT:
illegal flash address in cmd_flashupdate()
This error I would usually get when my Flash would have a size of <= 16 Megabyte, but I am writing after that address. The BT chip seems to get the correct size, because I get "128" back for REG_FLASH_SIZE.
Is there a compatibility issue with that Winbond flash? I checked this list and did not find any flash with 1Gbit size, which I need:
http://www.brtcommunity.com/index.php?topic=77.msg1658#msg1658I also changed the flash on my board to make sure that it is not damaged, but had the issue with 4 different pieces. Do you have any suggestions how to debug that or any information if that Winbond flash has been tested by someone already?
